Wind turbines - Part 26-1: Time-based availability for wind turbine generating systems

IEC 61400-26-1:2011(E) defines generic information categories to which fractions of time can be assigned for a wind turbine generating system (WTGS) considering internal and external conditions based on fraction of time and specifying the following: - generic information categories of a WTGS considering availability and other performance indicators; - information category priority in order to discriminate between concurrent categories; - entry and exit point for each information category in order to allocate designation of time; - informative annexes providing various examples.

Vetrne turbine - 26-1. del: Časovna razpoložljivost, ki temelji na proizvodnih sistemih vetrnih elektrarn (IEC/TS 61400-26-1:2011)

Ta del standarda IEC 61400 opredeljuje generične kategorije informacij, za katere je mogoče določiti deleže časa za sistem za proizvodnjo vetrne turbine (WTGS) glede na notranje in zunanje pogoje, ki temeljijo na deležu časa in določajo naslednje:
• generične kategorije informacij sistema za proizvodnjo vetrne turbine ob upoštevanju razpoložljivosti in drugih indikatorjev delovanja;
• prioriteto kategorije informacij, da bi razlikovali med sočasnimi kategorijami;
• vstopno in izhodno točko za vsako kategorijo informacij, da se določi čas
• informativni dodatki, ki vključujejo:
– primere izbirnih kategorij informacij,
– primere algoritmov za poročanje o razpoložljivosti in indikatorje delovanja,
– primere scenarijev uporabe.

WIND TURBINES –
Part 26-1: Time-based availability for wind turbine generating systems

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any d
